Question about 2003 Chevrolet Impala

1 Answer

Low oil pressure

I have a 1999 olds aurora. Changed the oil and filter, and the oil pressure relay switch..but when engine heats up LCD panel displays "low oil pressure" with accompanying alarm. This usually happens as I slow down and prepare to come to a complete stop. A quart of Lucas Oil with the oil change slows the problem down, but does not eliminate it.

Sounds like you have an internal engine problem. the only way to be sure is to check the oil pressure with an external gauge.

I have a 1995 olds aurora with a northstar. The oil level is fine but the computer says low oil pressure when at a stop light. Is this the oil sensor or oil pump?


Oil pressure is generally not related to oil level unless the oil level is low.
Oil pressure is created by a pump and as the engine parts wear over time, the oil passes through them easier causing oil pressure to drop.
It is also possible that the loss of pressure is caused by an oil pump that has worn, but don't get your hopes up.
If the vehicle has a lot of mileage, has been driven hard, has not had the oil changed regularly, this occurs.
It is sometimes possible to put additives in your car that are "thicker" than oil and this will give you some time to decide what to do.

2001 Auroro 3.5 V6 low oil pressure in display area and oil light come on shortly after start up then goes out when temperature gauge reads car is warm. Oil change shop says no leaks and they changed...


you have a cartridge filter on a 3.5, it is not a screw-on metal canister like most oil filters...the cover that has to be removed to take out and install the new cartridge is made of plastic and you might have a leak there-but I would suspect either the oil pressure sensor or the wiring or connector needs checking or cleaning. You should be using 5w-30 oil, and the capacity is 6 quarts. If you get a warning when cold that goes away when warm, it is not an engine problem but is a sensor problem, oil gets thinner as it warms, dropping pressure. Since your display trips when cold (higher pressure) it sounds like a sensor issue, and the module itself (the display on the dash) can also go bad on these cars.

100 psi is to much and will blow the seals in the motor.You need to find out what the oil pressure is suppose to be and if it is to low then replace the oil pump.

Oldsmobile aurora where is the oil sending unit.My daughter hit a curb with her car and now the the oil light is on and the on board computer say that she has low oil pressure .It is a 1999 V8 4.0 L ....


It should be on the left side of the engine(front of car) wiring runs under and around oil pan maybe wires are torn or pulled out of connector.oil sending unit is usually right in the same area of oil filter.

Have a 1999 Z71 chev truck with 5.3 L engine that has fluctuating oil pressure. Started with low oil pressure after start with engine clak that disappeared after it warmed up. Changed oil and found sludge...


In some cases where the oil is not changed properly, the oil pump screen maybe plugging or your oil filter is defective. Fram is a good filter. If there is no problem found, replace the pressure sensor.

Changed oil pressure switch,still no oil pressure


The fuel pump on that model runs through the oil pressure switch so that if the truck looses oil pressure,It kills power to the fuel pump to prevent engine damage.you need to find the cause of the low oil pressure reading(possibly a bad oil switch).That would be the cheapest place to start,or have it checked with a mechanical gauge.Good luck,
